My father is suffering from cerebral sinus thrombosis. They have blood clots in superior superior sagittal sinus & right transverse sinus. 15 days ago, they came across stroke, after stroke we had hospitalized them. Doctor gave him treatment of LMWH & now he is on xarelto for min. 2 years. Doctor said he have deficiency of protein C & S. And told us to check clotting status after 3 months. Now he is able to walk ,speak, and do all other activity as earlier. But still I need second opinion. Is possible to get reed of this clotting through operation or current treatment of Anti coagulation is right for them. Please suggest some specialist.
